Housing stock and density change what people search for.
The inner suburbs skew toward apartments, terraces and period homes, with work that is often access-constrained, heritage-sensitive and smaller in scope. The outer growth corridors are dominated by newer detached housing on larger blocks, where the same trade category means different jobs at different values. A single ad group serving both produces copy that fits neither. WIF segments where the job type genuinely differs and keeps things combined where it does not.
